LTC5548 IF current on Disabled

Question

On my application , i want to increase the signal streng of IF using a Trafo... something like that: 
 
 , On operation would be periods, when the mixer is deactivated. Is that mean, that during disabled or PowerDown , Is--> could be (3.3V/25Ohm) ~ 130mA? 
 So in short..is there current control or limitation during disabled? 
 
 i appreciate your comments sugestion or references

Hi, 
 From the schematic, 
 I can see a cap(c1) which will be shorting Vp to ground using transformer. 
 Also, I see you are using ADR16-6T transformer which is 1:16 core and wire transformer. Which means you are performing a step down conversion to a very low level(from 50ohms to 50ohms/16) which is completely mismatched. 
 All the current is going to the LO amplifier alone and when disabled, no current control is available to start with. 
 Thanks,
